"Since Skype was acquired by Microsoft, both entities have refused to answer questions about exactly what kinds of user data can be intercepted, what user data is retained, or whether eavesdropping on Skype conversations may take place," reads the letter, signed by such groups as the Digital Rights Foundation and the Electronic Frontier Foundation."
